CDI 9.11 Limited Edition: Black Frame

ESS will donate 25% of its sales from this product to the Stephen Siller Tunnel to Towers Foundation, whose charitable works benefit firefighters, EMS, law enforcement officers, and military personnel (see "25% Back" tab for details).

The resilient, battle-hardened CDI™ sunglass has a long track record of saving eyes and lives in hostile situations.

The ESS CDI's high-impact lenses can be easily exchanged for quick adaptation to your environment. Its high-speed low-drag frame and shatter-resistant lenses make the CDI™ comfortable and cool enough for downtime yet functional and rugged enough for the battlefield.

The CDI's Lateral Exchange System™ makes interchanging lens colors quick and easy. This product comes with exclusive Polarized Mirrored Gray lenses, but can accept any of the following five replacement lens options as well:

ESS strongly recommends the use of high-impact polycarbonate prescription lenses to optimize impact resistance in the CDI™ sunglass. High-impact polycarbonate prescription lens material will maximize the impact resistance of the system well beyond that offered by CR-39 resin or other common materials used in prescription lens manufacturing.

The tragic events of 9.11 have left a lasting impact on all Americans, especially those that protect and defend our country. In recognition of the everyday
sacrifices made by military, law enforcement and firefighting professionals, ESS is proud to donate 25% of sales from its limited edition Remember 9.11
products to the Stephen Siller Tunnel to Towers Foundation, whose charitable works support these heroes and their families.

The Stephen Siller Tunnel to Towers Foundation was created to honor the legacy of New York City firefighter Stephen Siller, who laid down his life at the World Trade Center on September
11, 2001 in order to save the lives of many others.

By raising funds through its now-nationwide 9.11 "Tunnels to Towers" runs, the Foundation promotes healing and provides hope by building customized homes for
severely-wounded combat veterans, assisting the families of fallen public safety officers, and helping firefighters recover in burn centers nationwide.

“I am writing to show and tell you of the in-field performance of the fantastic protective eyewear ESS has developed. The attached photos were taken before and after a sniper attack outside of Mosul, Iraq, on July 3, 2006. I was positioned in the right rear hatch of my rolling Stryker when a sniper that had claimed the life of a fellow soldier and good friend three days prior struck again. This time, the sniper's bullet hit my gun mount and continued on to fragment and splatter on the right lens of my ESS CDI sunglasses. While I was knocked down with the impact of the bullet, I suffered only minor injuries to my head and was back in action within the week. As strong testimony to the physical toughness of the CDI glasses, after the sniper attack I simply replaced the fractured lenses and continued to wear the glasses in combat for the remaining five months of duty in Baghdad. The frames were dinged a bit, but still functioned as new, even after taking a hit from a 7.62 sniper round.Many thanks to your product development department and all of those associated with making these fine products available to our brave young men and women that continue to fight the fight in Iraq and Afghanistan.”
